摘　　要：目的:探讨不同产地珠子参药材中无机元素的特征及与药材道地性之间的关系。方法:用ICP-AES法测定不同产地珠子参药材中无机元素的含量,采用SAS统计方法对珠子参药材中无机元素进行相关性分析、主成分分析和聚类分析。结果:珠子参药材质量与无机元素含量之间存在一定相关性;Fe、Cr、Al、Mg、Cd、Ca、Zn为珠子参药材的特征元素;珠子参药材无机元素含量存在地域性差异。结论:无机元素Ca、Fe、Zn(尤其是人体必须的微量元素Fe、Zn)含量可以作为珠子参药材品质的评价指标之一;陕西可能是珠子参药材的道地产区。Objective： To investigate the Daodi habitat of Panacis Majoris Rhizoma by analyzing the characteristics of inorganic elements in Panacis Majoris Rhizoma from different habitats. Methods： The contents of inorganic elements in Panacis Majoris Rhizoma from different habitats were determined by ICP-AES. The characteristics of inorganic elements in Panacis Majoris Rhizoma were analyzed by correlation analysis,principal component analysis and cluster analysis. Results： It was showed that there was a correlation between the contents of inorganic elements and the medicine quality of Panacis Majoris Rhizoma; Fe,Cr,Al,Mg,Cd,Ca and Zn were principal components of Panacis Majoris Rhizoma; and the contents of inorganic elements in Panacis Majoris Rhizoma existed regional differences. Conclusion： The contents of inorganic elements Ca,Fe and Zn,especially the content of the essential trace elements Fe and Zn,can be used as one of the key reference for medicinal quality evaluation of Panacis Majoris Rhizoma; as well,Shaanxi Province is probably the Daodi habitat of Panacis Majoris Rhizoma.
